Update Create Item workflow for Piece creation/edit

Overview: After discussing this issue we have concluded that the best solution will be to update the workflow for create item and select location. This will provide a more permanent solution for Goldenrod release

Approach:

• Remove the need for the "Add item" plugin by implementing a toggle that allows the user to tell FOLIO when to automatically create an item record for the piece.
• Update location selection to simplify user experience and prevent system errors

Acceptance criteria:
1)
Given user is creating a piece
When the POL "Create item setting" = Instance, Holding, Item
Then user can see a "Create item" toggle

2)
Given user is creating a piece
When the "Create item" toggle is true
Then system creates item when user clicks "Save and close" or "Quick receive"

3)
Given user is editing a piece
When the an item has already been created for the piece
Then Connected hyperlink displays instead of "Create item" checkbox

4)
Given user is receiving piece(s)
When the POL "Create item setting" = Instance, Holding, Item
Then user can see a "Create item" toggle

5) Barcode and call number not being added to item successfully
Given user is receiving piece(s)
When the "Create item" toggle is true
Then system creates item when user clicks "Receive"

5)
Given user is receiving piece(s)
When the an item has already been created for the piece
Then Connected hyperlink displays instead of "Create item" checkbox
